arry out the mission. This enti- therefore, accounts for the fact t, as the waterjet is larger and re efficient, it is also heavier d it impacts the ship weight and ag to a point where the fuel quired may be higher than that th a smaller jet.

The naval architect who knows

DW to estimate the performance fa waterjet in relation to the ship esign may be better equipped to elect the waterjet size than a vaterjet manufacturer whose nterest may be to maximize the relative efficiency of the jet regardless of the overall ship design optimization.

Optimized Integration of Hull and Propulsor."

The paper was presented at the Fast '95 con- ference, authored by John L. Allison and

ABB Stal To Provide Gas

TuHtines For Ferry

ABB STAL AB, Sweden, has received an order for two GT35 gas turbines to be used for the propul- sion of high-speed ferry Buquebus

B60. The ferry will be built at

Spanish shipyard E.N. Bazan in

San Fernando. ABB Stal will also be responsible for supplying the ferry's automation system, while

ABB Stal and Bazan will share the delivery of the electrical equip- ment.

Buquebus B60 is designed for a cruising speed of 60 knots, which will reportedly make it the world's fastest car/passenger ferry in reg- ular service.

Combined, the two gas turbines will develop a shaft power of 34,000 kW. The gas turbine sys- tem has been developed to operate on IF 30-type intermediate fuel oils to achieve low operating costs.

Upon completion, the ferry will enter into regular service on the route between Buenos Aires,

Argentina, and Motevideo,

Uruguay, at the end of next year.

Rico Granted Patent Ponding

Status Of Speed Nozzle

Rice Propellers, located in the

North Pacific coast of Mexico, is a major supplier of propellers and nozzles for U.S. shipyards and fish- ing fleets. The company has recently developed the Rice Speed

Nozzle design and the Skewed

Kaplan Propeller. Rice has been granted patent pending status from the Patent and Trademark

Office of the U.S. Department of

Commerce. The Rice Speed Nozzle is reportedly a completely new design. The inside and outside shells are cambered and rounded.

With these nozzles, users can reportedly obtain maximum thrust without losing free running speed.

In 1995, Rice Speed Nozzles were installed on 140 boats in the U.S. — mainly in the Gulf of Mexico and the East Coast. So far, in 1996, the nozzle has been installed on more than 90 boats.
